Abstract

The invention relates to an insulation backboard for a solar photovoltaic module, and belongs to the technical field of solar photovoltaic cells. The insulation backboard comprises a weather-resistant layer, an electric insulation layer and an adhesive layer, and is characterized by further comprising a blocked layer arranged between the weather-resistant layer and the electric insulation layer, wherein the surface of the blocked layer facing the weather-resistant layer is combined with the weather-resistant layer through a first bonding layer, the surface of the blocked layer facing the electric insulation layer is combined with one surface of the electric insulation layer through a second bonding layer, the other surface of the electric insulation layer is combined with the adhesive layer through a third bonding layer, the weather-resistant layer is a mixture of polyvinylidene fluoride and acrylic acid resin and an inorganic material, the blocked layer is an aluminum foil or a polyethylene glycol terephthalate film, and the electric insulation layer is polyethylene glycol terephthalate, poly (ethane ethylene 2,6-naphthalate) or polyamide. The insulation backboard can increase steam obstruction effect and ultraviolet resistance, ensure the service life, enhance the steam obstruction effect, and meet the requirement for industrialization scale production without dependence on import.

Description

technical field

[0001] The invention belongs to the technical field of solar photovoltaic cells, and in particular relates to an insulating backboard used for solar photovoltaic modules. Background technique

[0002] As is well known in the industry, the overall structure of a solar photovoltaic cell includes: a frame (usually using an aluminum frame), a solar photovoltaic glass installed on the frame, and a battery sheet (also called a silicon wafer or silicon plate) located under the solar photovoltaic glass. ), hot melt adhesive layer (EVA layer), junction box and insulating backplane. Since solar photovoltaic modules are usually installed outdoors, it is undoubtedly required to have ideal weather resistance. The United States has established a goal of 30 years of service life for solar photovoltaic (PV) components, so in addition to strict technical requirements for sealants used in PV components (technical requirements such as: resistance to high and low temperature en...
